shenyu 2.4.2 1.login your shenyu-admin web 2.PluginList-->Proxy-->SpringCloud-->RulesList-->Modify-->Handler-->timeout default 3000ms 3.Set timeout parameters

For other versions, perform similar operations. Configure your rules.

case1: shenyu.httpclient.readTimeout=3000 shenyu.httpclient.writeTimeout=3000

rule timeout：10s

provider server sleep：8s

error：io.netty.handler.timeout.ReadTimeoutException: null

case2： shenyu.httpclient.readTimeout=10000 shenyu.httpclient.writeTimeout=10000

rule timeout：10s

provider server sleep：8s

invoke success

case3：

shenyu.httpclient.readTimeout=10000 shenyu.httpclient.writeTimeout=10000

rule timeout：3s

provider server sleep：8s

error：Resolved [TimeoutException: Did not observe any item or terminal signal within 3000ms in 'peekTerminal'
